Subject: [PATCH AUTOSEL 6.1 20/33] ASoC: Intel: avs: Account for UID of ACPI device

From: Cezary Rojewski <cezary.rojewski@...el.com>

[ Upstream commit 836855100b87b4dd7a82546131779dc255c18b67 ]

Configurations with multiple codecs attached to the platform are
supported but only if each from the set is different. Add new field
representing the 'Unique ID' so that codecs that share Vendor and Part
IDs can be differentiated and thus enabling support for such
configurations.
